GUEST:
It belonged to my great-aunt, and when we were kids visiting, we'd admire it. And she eventually gave it to my brothers and I. And with a little bartering on my part and their part, I ended up with it.
APPRAISER:
What have you discovered about it?
GUEST:
Well, I was at a store where they restored slot machines, and I looked it up and they had a Totem. No picture, just a... _ Totem. And it gave a value of perfect condition around $10,000.
APPRAISER:
Well, it is a very, very rare machine. When I saw this on the table, I was really quite taken aback. It is an early slot machine and it is the Totem. And it was made by one of the great makers of slot machines, the Watling Manufacturing Company. They made some of the best and most unusual slot machines. These date from around 1910 and then forward. After the slot machine business disappeared, they ended up making nothing but penny scales. And I remember over 40 years ago I bought an old penny scale and I called up the Watling Company to get a footplate and I spoke to the old man Watling himself. It's a great old company, and this is a rare survivor with its original glass. See, this is reverse-on-glass decals. If this were damaged, it would really radically affect the value. It also has the original payout paper. All of these are little details that really help in the value. There is one problem with the machine, and that is that it does have a replacement rear door, but that is a small problem when considering the rarity. It has all the working mechanisms. It's a really complex piece. And another thing that makes this a very rare machine... you know most are three reelers. This has a double arrow action. We put the nickel in here, and they can see that there's a real nickel and not a slug. That was part of the security measures.
GUEST:
Right.
APPRAISER:
And then you pull this knob down... and if you match up the fruit, you get some nickels back. Not bad, eh?
GUEST:
You have good luck.
APPRAISER:
So, now, your research suggested that if it were in perfect condition it would be worth about $10,000. Well, this is really not perfect condition, but for a machine of this rarity, it is in extraordinary condition. I've done a little research and I think a conservative auction value in today's market is in the $25,000 to $30,000 range.
GUEST:
Whoa. That's considerably more than I anticipated.

I think you're going to have a little more trouble with your brother.
Slot machines are the most popular game in modern casinos. If you’ve never seen one, a slot machine resembles an arcade game that has a lever on its side. For a small fee you can pull the lever, and the machine will generate a random combination of three symbols. If the correct combination appears, you can win a prize, maybe even the jackpot.
Slot machines make fantastic profits for casinos because they offer a very low payout rate. In many games, such as Blackjack and Roulette, the odds are only slightly stacked in the casino’s favor. In the long run, the casino pays back 97 to 98 cents in prizes of every dollar that a gambler spends on these games. With slot machines, it is typical for a casino to only pay back 90 to 95 cents—and the casino keeps the rest. If this seems underhanded, keep in mind that slot machines are one of the most popular games at a casino; few people seem to mind. And if you consider that state lotteries have payout rates that are much closer to 50 cents on the dollar, slot machines don’t look that bad.
Slot Machine Object Invasion Games
In this project, you will build a real, working slot machine modeled after some real life Video Lottery Terminals from Manitoba, Canada. The terminals were a source of scandal in the 1990s. You’ll get to the bottom of this scandal by writing a program that recreates the slot machines. You’ll then do some calculations and run some simulations that reveal the true payout rate of the machines.
This project will teach you how to write programs and run simulations in R. You will also learn how to:
